Surface web,Deep web and dark web

Hello guys, This is Anand Kumar and today we would learn about types of the web in this blog. 

Internet:
Internet is nothing but a network through which we can share data from one to another. The Internet is medium to share data. The Internet is used to connect with other devices




 
Surface web:(Also known as public web and visible web)

The content which we can visit on the internet or web or on google they are called the surface web for example if you search for some password-protected sites or data the Google would not list them for you.
The total percent of the surface web which we use as in normal web searches is only 4℅.

The best example of the surface web is a client and server architecture. 






















Deep web:

The deep web is a part of the internet which is not indexed by search engines.
The content of the website which is protected using passwords and encryption comes under this category.


Dark web:

These types of webs are used for illegal works such as selling drugs (criminal activities) 
To access these types of the web you need an anonymizer browser such as Tor.


Indexing of the website means collecting information from the website and storing it on their server.

You might be thinking that how come google knows about all the websites which are available on the internet it's by using spiders, what spider does is it scans a website and all the hyperlinks present on a website and store it on their server or database this is called indexing.

This virus definition consists of a new virus hash values and signatures.
